Introduction to Dymension and Rolapps

The Internet of RollApps represents a revolutionary network, comprising RollApps (layer 2s) and the foundational Dymension Hub (layer 1). These RollApps, designed as easily deployable modular blockchains, seamlessly integrate with the Dymension Hub, offering them crucial elements of security, liquidity, and connectivity.

Why Dymension?

In the realm of cryptocurrency applications, there's an urgent need for simplicity and economic sustainability. The recent success of rollups has showcased a straightforward business model: profits equal fees minus base layer costs. However, this success has resulted in a proliferation of layer 2 solutions, each with its bespoke implementation, multi-sig bridge, and security assumptions. This fragmented approach has led to an uncoordinated, insecure, and chaotic user experience, diluting the advantages initially associated with rollups and modular blockchains.

How Dymension Solves This

Dymension brings order to this chaos by standardizing rollups through the Inter-Blockchain Communication Protocol (IBC), akin to how tokens were standardized with ERC. Introducing RollApps as a new crypto primitive, Dymension consolidates the rollup business model, speed, and scale into a unified and user-friendly experience, paving the way for the true emergence of an Internet of RollApps.
RollApps, as modular blockchains, eschew the maintenance of costly validators. Instead, they leverage the Dymension Hub (layer 1) for securing funds and rely on Data Availability (DA) networks for publishing transaction data.

Building Blocks of Dymension

Security

Central to Dymension is IBC, a battle-tested bridging protocol enabling secure communication between different chains. RollApps seamlessly connect to the IBC economy via the Dymension Hub, analogous to how a server connects to the internet through an internet service provider. Dymension replaces centralized and risky multi-sig bridges prevalent in Ethereum and L2 ecosystems with IBC-connected rollups, ensuring that funds deposited into a RollApp are as secure as the Dymension Hub itself.

Liquidity

The Dymension Hub incorporates an embedded liquidity layer, facilitating asset pricing, swapping, and efficient token routing across the ecosystem. This not only promotes economic growth but also ensures a smooth user onboarding experience to RollApps and easy access to RollApp tokens.

Data, Scale, and Costs

RollApps publish transaction data to external blockchains like Celestia, Avail, NEAR, and others to provide verifiability. RollApps can intelligently choose the best blockchain for their data based on factors such as costs, values, and technology. This competition fosters a data market vital for scaling the data requirements of the entire Internet of RollApps.

Crypto UX

Dymension envisions the future of crypto UX as a simple three-step process: deposit, play, withdraw. The infrastructure streamlines this process at scale, enabling developers to deploy RollApps with a few clicks using the Dymension RollApp Development Kit (RDK). Users can effortlessly deposit from Ethereum and across the broader crypto ecosystem with a single transaction routed through the Dymension Hub.
In essence, Dymension is not just a solution; it's a transformative force shaping the future landscape of decentralized applications and providing users and developers alike with a seamless, secure, and interconnected experience.
